Sizes for multi cutter segments are similar or same to sizes for single blade cutter, the main differences on formula of the segments (metal bond and diamond density).
2. Production application of granite multi block cutter segments
In the market, as per the saw blade diameter combination differences, there is two type of granite multi block cutter in use. One is all blade sizes in one same diameter, we call it single size multi blade block cutter or European/Italian multi block cutter, the other is all blades sizes in two or more different diameters, we call it multi size multi blade block cutter or Chinese multi block cutter.

4. What cutting parameters do you recommend for multi cutter segments?
For multi block cutter, users are recommended to travel at fast speed while at small step cut down (down feed depth as you may call). Max. Cutting speed or 2-4m/min for traveling speed and down feed depth at 1-2mm as per segment sharpness.
Different from single blade block cutter, saw blade receive higher cutting impact and frictions from granite block when cutting through granite blocks, so diamond tools manufacturers design multi cutter segments with better sharpness and less density of diamond powder to make it suitable for fast cutting and less down feed to balance the impact and frictions from the block to the machines.
Besides impact consideration, less down feed helps remain diamond open and not easily get dull caused by diamond particle fall down when cutting with bigger down feed.
